So I ended up using two relays. The issue I was getting is that the power going to the motor was reading only 2.5V regardless of the amount of power I try to send it. I tried 3.3v, 5v and 9v and all of them gave 2.5v at the motor. The only thing I could do correctly on this circuit was to get two LED's to turn on when I push the button. Thank you for the help everyone! I tried to understand some of the other methods that some people gave but I just didn't seem to understand them to well.

Thank you for the tip! I would be scratching my head on this one because the GPIO pins can't put out enough current to control two transistors at once. So I would need a GPIO pin per transistor.

So I finally got home and started testing my setup, I figured out that the GPIO doesn't put out enough power to power the gate (base) so I need a GPIO pin to each gate in order to make my circuit to work correctly. Thank you for your help and information you gave everyone!

Will do! I think I got it work the way I want by testing first with LED's first.

I will have to look into it. They look like they cover all the GPIO pins and I would need to figure out how to hook up buttons to tell the Pi to turn either turn on GPIO 14 or GPIO 15 to control the rotation of the motor.

No I do not have PNP transistors. I will have to look up what EE reasons and H-bridge up to get a better understanding. Thank you for letting me know!

Ya that is what I will try to avoid. Thank you for bring H-bridge up because I haven't heard of this before! I was thinking if button = pressed : while button = pressed: turn on GPIO 14 turn off GPIO 14

Thank you!

I am using 3-6v DC motor. Sorry I forgot to add that in my post. Thank you for your response!

I'm working on my final project and my professor will be out until finals are over. I am using 2N2222A NPN Transistors to power a DC motor to turn clockwise or counter clockwise. I created a diagram of how I would think it will work bunt I don't want to build it and find out it blows something up. I haven't had any electrical engineering classes and this is a computer architecture class. In a way this is the first I am creating my very own circuit and not just copying off from one of my labs. I did not have a lab that worked with transistors or making a DC motor turn clockwise or counterclockwise. If you can, please let me know if this will work or what I will need to change to make this work.

It should be equivalent to a 24" 1080p when comparing pixel density. If you want a bigger screen, video will look fine but you will notice a different in text and rely more on AA for gaming. If you use a Nintendo Switch on it, just remember the switch will only scale up to 1080p and not 1440p (edit) but you have a lower response time so the games will feel more responsive on the monitor versus a TV.

Just remember that larger means lower pixels density. 1440p at 32" is about the same as 1080p at 27". It isn't bad, but it's noticeable. I found that 24" at 1440p to be the sweet spot for me but everyone is different. If you want color accuracy, Benq BL series is really nice with a really good stand. It should be around that price

I brought a Samsung CRG90 monitor. The weird thing I noticed is that if I run at 120Hz or higher (OC it 144Hz) at 5120 × 1440, it only supports 8 bit color. If I run the same resolution at 100Hz or lower, it will use 10 bit color. I personally dont mind losing 20 Hz for more color because I generally play games that are geared towards looks and story than speed and skill. I mostly brought this monitor because it supports 32:9 1440p, HDR 1000 nit, and higher refresh rate for a smoother video/gameplay. I'm wondering if people would take the higher refresh rate with 8 bit color or take the 10 bit and lower refresh rate?

If heat is any issue, I have a 2700X running at 3.8 GHz at 1.1V You can see if you can run stable at these settings on Ryzen 2 CPU's.

That's what I thought. Thanks!
